DS had the WISC IV done shortly after he turned 6 and had a traumatic brain injury. He had had the WPPSI done when he was 3 but he was so young and uncooperative that I never really took the results that seriously (he didn't even finish the test). The WPPSI was done because of developmental delays. Then the WISC was done after the skull fractures/brain injury but I didn't know the neuropsych was going to do any IQ testing. When I figured out that's what he was doing (the test was sitting there) I was hoping he'd come out somewhere above 100, esp. considering he was still affected by the brain injury with poor motor skills and impaired vision (I really wasn't expecting great scores from him, I just would have liked to see something that was at least 50th percentile), so everyone was surprised by the perceptual reasoning score of 141. His GAI was in the 130's.
DD took the CogAT in second grade with disastrous results (she didn't finish half the test), and she needed an IQ test for possible entrance into the gifted program. I didn't want the school district to do it so I took her to have it done privately. I was hoping she'd score at least 132 and her GAI turned out to be 150+. I see her and DS as very similar in terms of their non-verbal ability so I was expecting high scores from her based on his results, I just wasn't sure how high. She did much better than him in verbal ability which I was expecting as well.
My guess is if you think he is HG, he probably is. Both of my kids scored higher than what I would have expected (on the WISC at least).
I don't know my own IQ and don't really care, but my PSAT scores were around the 97th-98th percentile, which is the closest thing I've taken to an IQ test. I don't remember my GRE scores. I show an opposite pattern than my kids in that my verbal ability is stronger than math/non-verbal.
